Welcome to the PC, Dan!
Haha, yeah, it can be confusing! There's so many to track off and will be more confusing if you haven't caught up - I somewhat still haven't but I'm getting there, lol. Also, there's a lot of topics that might help clear the confusion! Want a full heal? Wait but you might even get more confused... uh-
ANYWAY - lol - enjoy your stay here and feel free to ask questions! ~
